Introducing the Honeywell SS30AT Bipolar Hall-Effect Magnetic Position Sensor, available in a subminiature SOT-23 surface mount package that takes up less space on the printed circuit board (PCB). Available on tape and reel, the SS30AT often allows for lower-cost pick and place assembly, helping to reduce manufacturing costs.

The SS30AT is a very small, versatile, digital Hall-effect device operated by the magnetic field from a permanent magnet or an electromagnet designed to respond to alternating North and South poles.

The SS30AT sensor is:

Price competitive: Honeywell has optimized the size of the integrated circuit, saving on manufacturing costs while still meeting customer requirements. These cost savings result in lower costs to customers.

Economical: Package is supplied on tape and reel, often allowing for automated, lower-cost pick and place assembly which helps the customer to reduce manufacturing costs.

Small: Small footprint takes up less space on the PCB, typically allowing for more components on the same board.

Flexible: Synching output with open collector allows the sensor to interface with many electrical components without buffering; 4.5 Vdc to 24 Vdc supply voltages and operating temperature to 125 °C [257 °F] enhance application flexibility.

Stable: Thermally balanced integrated circuit provides stable operation over a full temperature range.

Safe: Built-in reverse voltage protection provides enhanced circuit protection.

Potential transportation and industrial applications include speed and RPM sensing, tachometer, motor and fan control, electric vehicle control, convertible roof position, flow-rate sensing, brushless dc motor commutation, and robotics control.
